<p>A. 3x<sup>2</sup> + 8x - (4)<sup>2</sup> = 0</p>

<p>3x<sup>2</sup> + 8x - 16 = 0</p>

<p>3x<sup>2</sup> + 12x - 4x - 16 = 0</p>

<p>3x(x + 4) - 4(x + 4) = 0</p>

<p>(3x - 4)(x + 4) = 0</p>

<p>x = 4/3, -4</p>

<p>B. x<sup>2</sup> + 11x + 28 = 0</p>

<p>x<sup>2</sup> + 7x + 4x + 28 = 0</p>

<p>x(x + 7) + 4(x + 7) = 0</p>

<p>(x + 4)(x + 7) = 0</p>

<p>x = - 4, -7</p>

<p>C. 2x<sup>2</sup> - 15x - 17 = 0</p>

<p>2x<sup>2</sup> - 17x + 2x - 17 = 0</p>

<p>x(2x - 17) - 1(2x - 17) = 0</p>

<p>(x - 1)(2x - 17) = 0</p>

<p>x = 1, 17/2</p>

<p>Now, according to the question</p>

<p>Sum of the square of negative roots = (-4)<sup>2</sup> + (-4)<sup>2</sup> + (-7)<sup>2</sup> = 16 + 16 + 49 = 81</p>
